Looks like they're going to drag out the Trump immunity opinion till Monday

7. SCOTUS precedent gives them immunity for all acts taken during official proceedings

Stump vs Sparkman and Mireles v. Waco are the 2 main cases.

Judges cannot be sued over actions taken in the course of their official duties or over actions taken during proceedings. They have immunity over official acts, but can still be sued and found liable for things outside of official acts.

Edit:

Should be noted, that even without the precedent, it would be difficult to establish standing to bring suit against them. It would also be near impossible to prove that they are purposely delaying in order to affect the election.
